Benefits of technology

[0008] The present invention provides an apparatus and method of providing fingertip haptics of visual information using an electro-active polymer, which can allow a user to feel a texture of a surface of an object and a sense of touch of the object by providing force feedback and tactile feedback by moving and deforming the polymer inserted in a touch panel of an image display device.

Problems solved by technology

In order to improve the performance of the haptic interface to increase a degree of freedom for realizing the reproduction of the movement, the connecting mechanism of the mechanical links becomes complicated, increasing the weight of the device to cause an inertia problem.
As mechanically driven actuators are added to the device, the size of the device is increased to be limited in its application or operation.
Additionally, in order to accurately transmit the haptic information, the number of actuators must be increased, thereby making the structure of the device more complicated.

Embodiment Construction

[0020] Exemplary embodiments of the present invention will be described more in detail hereinafter with reference to the accompanying drawings.

[0021]FIG. 1 shows a schematic block diagram of a device for providing fingertip haptics of visual information, according to an exemplary embodiment of the present invention.

[0022] The inventive device includes a control unit 100, a sensing unit 130, an electro-active polymer (hereinafter referred to as “polymer”) 140, a pattern generating unit 150, and a database 160.

[0023] The control unit 100 is designed to move the polymer 140 based on a detecting signal from the sensing unit 130 and deform the polymer 140 based on a pattern signal generated from visual information. The control unit 100 is comprised of a polymer movement control unit 110 and a polymer deformation control unit 120. The polymer movement control unit 110 moves a contacting point by applying a first driving voltage to the polymer 140 based on location information of the to...

Abstract

An apparatus provides fingertip haptics of visual information using an electro-active polymer for an image display device. The apparatus includes a sensing unit which outputs a detecting signal by detecting a user's finger touching a surface of a touch panel; a pattern generating unit which generates a pattern signal of haptic information from the visual information based on the detecting signal, and a control unit which moves the electro-active polymer based on the detecting signal from the sensing unit and deforms the electro-active polymer based on the pattern signal from the pattern generating unit.

Description

BACKGROUND OF THE INVENTION [0001] This application claims priority from Korean Patent Application No. 10-2004-0094209 filed on Nov. 17, 2004, in the Korean Intellectual Property Office, the disclosure of which is incorporated herein in its entirety by reference. [0002] 1. Field of the Invention [0003] Apparatuses and methods consistent with the present invention relate providing fingertip haptics of visual information, and more particularly, to providing fingertip haptics of visual information using an electro-active polymer for an image display device. [0004] 2. Description of the Related Art [0005] Haptic is a sense of fingertip touch that people feel when touching an object. The haptic includes tactile feedback that can be felt when a person's skin contacts a surface of the object and a kinesthetic force feedback (hereinafter referred to as “force feedback”) that can be felt when a movement of a joint and a muscle is disturbed. [0006] The study of transmitting haptic information...
